the top of a railway-car and the Ventilating devicestherein; Fig.' 2, aperspeetive view of a portion of the top of a railway-car,

showing an end view ofthe ventilating air-` chamber; Fig. 3, a side elevation of one of the Windows, showing the deiiectors, their connections, and method of operation; and

Fig. 4, a vertical section on the line w .fr of Fig. 3.

In all the figures similar letters represent similar parts.

The invention consists of an air-chamber arranged in or upon the raised deck or roof of a railway-car, and along nearly the entire length of the same, with broad daring ends,

having adjustable cut-oft gates therein, and a series of registers or holes in its under side opening into the chamber of the car 5 also, ot'

a series of deflectors hinged at the sides of thel windows, and ot a drop-sash attached to the lower end ot' the wiudow'sash, the deiiectors being operated by certain novel contrivances,

A f l as hereinafter explained.

The object of the invention is to thoroughly ventilate a railway-car, when in motion, by having currents of air passthrough an air- 'chamber in its roof, and then into and through the body of the car, and, at the same time, to keep it free from dust, cinders, smoke, dto. y

` To accomplish this an air-chamber, A, extending nearly the Whole length ot'the car R,is

constructed in or upon the root' or raised deck G of the same, as clearly shown in Figs. 1 and 2. The ends G of the chamber reach over a portion of the sloping ends ot' the de ck G, and their sides are made daring, so as to give or present a broad open mouth for catching or receiving the air when the car is in motion, as shown in the same figures. Across the ends or mouths of the chamber wire-gauze screens I are placed, as shown, to prevent the entrance of dust, smoke, cinders, or other foreign substances, and in them are pivoted or hung gates D, arranged to be operated by means of a lever, F, provided with a ball-jont-that is, an arm, E, having a ballon itsend--or with any other suitable device 'for adjusting `the gates at any desired angle, or for closing` them entirely, so as toadmit the passage of any desired volume of air, or to cut ott' the same. In the under side of the air-chamber are a series of registers or holes, B, opening into `the body of the car. On each side ot' each of the windows detlectors J, made of metal or of glass with metallic frames, are fixed .in a vertical position, so as to swing on gudgeons Working in brackets on the sides of the Windows, as shown in Fig. 3. They are connected, by. links P P, to a rod or bar, M, arranged horizontal- 1y on the side of the car, so to be moved longitudinally by means of a lever, N, pivoted to the body of thecar at O, as shown in the sa-me figure. 4These detlectors are so connected to the bar M that in Whichever direction it moves, all on the same side of the Windows Will have .the same relative motion andv position as regards each otherthat is, by the same movement of the bar, the detlectors on the same side of all the windows Will have the same position. The breadth of the deiectors is about equal to one-fourth of the breadth of the window, and their height` about that to which the sash is usually raised, as shown in Figs. 3 and 4. The lower side of the windowsash L has attached to it a drop sash or shelf, K, in such a manner that it Will turn up against ,the Window-sash whenit is down, but when the latter is up Will turn out and extend over the top of the deiectors, as clearly shown in Fig. 4.

The operation of these devices will. now be readily understood. When the car is in motion, the front gate ofthe air-chamberis opened, and the one in the opposite end closed. At the same time the detlectors on the side of the windows in the direction in which the car is moving are placed at an angle of about forty-tive degrees,whilc those on the opposite take a position parallel with the side ofthe vcar and the `Window-sash. If the latteris raised, the drop-sash Willextend over the` deiiectors, as shown. Whenthe parts are thus adjusted and the car in motion, the air r will pass in large volume into the air-chamber and be distributed through the body of the car, as shown by the arrows in the drawings, and will pass out through the windows. At thev same time the smoke, dust, sparks, cinders, 8vo., tlying along the side of the car, will be turned from the Windows by the deectors and carried away by the currents ot' air passing out of the same, while the dropsash will either catch or turn away such as would incline to come in from above.

It is` obvious that the gates and deilectors may be adjusted as required, and that the airchamber may be constructed in or upon the roofs or decks of cars already built, or may be made an integral part of the same when constructed originally.

Having thus described my invention, what l claim isl. A Ventilating air-chamber, A, constructed in or upon the raised deck or root` of a railway-car, as herein described, with broad ilaring ends C, flush with or below the level of the top ot' the car,vprovided with adjustable gates D, and a series of holes, B, opening into the body of' the car, as and for the purpose set forth.

2. In combination with the deectors J, the devices for operating the same, consisting of the links P P, bar M, and lever N, as described.

3. [n combination with the dedectors J and window-sash L, thedrop-sash K, constructed and arranged substantially as and for the purpose set forth.

4. 'The combination of the Ventilating airchamber A, constructed and arranged to operate as described, with the drop-sash and deectors at the windows, constructed and operating substantially as set forth.

The above specification of my said invention signed and witnessed, at Chicago, this 16th day ot' December, A. D. 1875.
